<https://sourceware.org/ml/libc-alpha/2019-05/msg00630.html> <https://sourceware.org/ml/libc-alpha/2019-06/msg00015.html> I think realistically this is needed for the Y2038 work as well if we want to support building glibc with older kernel headers. “glibc 2.31 will have Y2038 support and rseq support, but only if it runs on a current and it happens to have been built against sufficiently recent kernel headers” is a bit difficult to explain. The current kernel part is easy enough to understand, but the impact of the kernel headers on the feature set has always been tough to explain. Especially if you factor in vendor kernels with system call backports. Thanks, Florian
